I just discovered poe2 trade. How cost of items changes over time for tjose that know poe ? Are items selling at higher or lower craft materials price ?
Creative in Poe is random
You can get lucky, or not. Your profit will very based on that.
Price of items is determined by supply and demand (and price fixing)
If a very strong build is found and becomes popular, items linked to that will skyrocket in price usually.
As supply meets demand, prices will fall again.
For basic introduction to trading, read https://maxroll.gg/poe2/resources/trade-in-path-of-exile-2
I don’t think there is a centralized database that tracks PoE 2 pricing data overtime like there is for PoE yet.
But one thing you should get is an add-on that allows you to check item price in-game based on everything listed in the trade site. https://github.com/Kvan7/Exiled-Exchange-2 allows you to quickly decide what’s worth stashing and selling and what is not until you get more practice and be able to judge it at a glance.
I imagine pricing will stay extremely dynamic during the whole early access, since many tweaks are expected.
